I have images as anchored objects in ID 2014 and choose to export the images in HTML as original or optimized jpg. I can export PDF and the images show up as expected. However, from yesterday, the images in exported HTML showed up as a place holder image (a grey block with a big check sign, see below). I checked the image files in the image folder created by ID during export and found they are the place holder images (see below). So it is not a problem of missing link. I upgrade to ID 2015, which did not solve the problem. I also tried changing view from fast performance to typical view in vain.
